Focused ultrasound to diagnose HIV-associated tuberculosis (FASH) in the extremely resource-limited setting of South Sudan: a cross-sectional study
2019
ObjectiveOur cross-sectional study aimed at evaluating the diagnostic performance of Focused Assessment with Sonography for HIV-associated tuberculosis (FASH) to detect extrapulmonary tuberculosis in extremely resource-limited settings, with visceral leishmaniasis as a differential diagnosis with overlapping sonographic feature.DesignCross-sectional study.SettingVoluntary Counselling and Testing Centre (VCT) of Yirol Hospital, South Sudan.ParticipantsFrom May to November 2017, 252 HIV-positive patients out of 624 newly admitted to VCT Centre were registered for antiretroviral treatment. According to the number of trained doctors available to practise ultrasound (US) scan, a sample of 100 pa…
The clinical use of statistical permutation test methodology: a tool for identifying predictive variables of outcome.
2015
<b><i>Objectives:</i></b> To identify the predictive variables affecting the outcome after radical surgery for bladder cancer by a newer statistical methodology, i.e. nonparametric combination (NPC). <b><i>Methods:</i></b> A multicenter study enrolled 1,312 patients who had undergone radical cystectomy for bladder cancer in 11 Italian oncological centers from January 1982 to December 2002. A statistical analysis<b> </b>of their medical history and diagnostic, pathological and postoperative variables was performed using a NPC test. The<b> </b>patients were included in a comprehensive database with medical history and cli…
Computerized tomography: an unreliable method for accurate staging of bladder tumors in patients who are candidates for radical cystectomy.
1989
A total of 164 patients with bladder tumors underwent preoperative staging by computerized tomography. All patients were previously untreated, or had undergone only transurethral biopsy or resection of the tumor before computerized tomography. The post-cystectomy histological stage was compared to the preoperative computerized tomography stage. Computerized tomography accuracy according to the tumor, nodes and metastasis classification was only 32.3%, whereas overstaging was found in 39.6% and understaging in 28.1% of the cases. In untouched tumors or after transurethral resection computerized tomography accuracy demonstrated no significant difference. Only 2 of 19 true positive lymph nodes…
Cancer-specific survival after radical cystectomy and standardized extended lymphadenectomy for node-positive bladder cancer: prediction by lymph nod…
2009
OBJECTIVE To investigate the associations between different overall or topographically restricted lymph node (LN) variables and cancer-specific survival (CSS) after radical cystectomy (RC) and extended LN dissection (LND) with curative intent in patients with LN-positive bladder cancer. PATIENTS AND METHODS Between 2001 and 2006, 152 patients had RC with standardized extended LND for bladder cancer with curative intent. Patients with positive LNs were stratified according to the median of the LN variables (LNs removed, number of positive LNs, LN density). CSS was related to overall and topographically restricted LN variables, e.g. different levels of LND, and relationships were tested by un…
Radical cystectomy with or without adjuvant polychemotherapy for non-organ-confined transitional cell carcinoma of the urinary bladder: prognostic im…
1996
To analyze the effectiveness of adjuvant polychemotherapy after radical cystectomy for non-organ-confined transitional cell bladder cancer (Stages pT3b, pT4a, and/or pN1 or pN2).Of 166 consecutive patients undergoing cystectomy at two institutions from 1987 to 1993, 80 received adjuvant polychemotherapy with methotrexate, vinblastine, and cisplatin plus doxorubicin (MVAC) or epirubicin (MVEC), whereas 86 had cystectomy only. The patients were evaluated for relapse-free survival and length of progression-free interval on the basis of follow-up data obtained in 1995 and 1996.Kaplan-Meier analysis revealed a significantly higher progression-free rate for patients after adjuvant chemotherapy (P…
Adjuvant polychemotherapy of nonorgan-confined bladder cancer after radical cystectomy revisited: long-term results of a controlled prospective study…
1995
A total of 83 patients with nonorgan-confined bladder cancer with or without lymph node metastases (tumor stages pT3b, pT4a and/or pN1, pN2) was evaluated in November 1993 for relapse-free and overall survival. All patients underwent radical cystectomy between 1987 and 1991, 38 underwent adjuvant polychemotherapy with methotrexate, vinblastine and cisplatin plus doxorubicin (M-VAC) or epirubicin (M-VEC). Of the 83 patients 49 had entered a prospective randomized trial comparing adjuvant to no adjuvant treatment. The protocol was activated in May 1987. Patient recruitment was concluded in December 1990 because an interim analysis of the 49 randomized patients revealed a significant prognosti…
Epidemiology, comorbidities, and healthcare utilization of patients with chronic urticaria in Germany
2021
Background. Comprehensive data on the epidemiology and comorbidities of chronic urticaria (CU) in Germany are either limited, or not contemporary. Objectives. To investigate the epidemiology of CU, overall comorbidities and healthcare resource utilized by patients with CU in Germany, using an anonymized statutory health insurance (SHI) database. Methods. Anonymized SHI claims research database of the Institute for Applied Health Research, Berlin [InGef] (01 January 2015-30 September 2018) was used to analyse insured individuals with a confirmed diagnosis of CU (ICD-10-GM codes). Twelve-month diagnosed prevalence and incidence, comorbidities (vs. atopic dermatitis and psoriasis), and healthc…
Pulmonary embolism location is associated with the co-existence of the deep venous thrombosis.
2019
Multiple studies have shown that in approximately half of individuals with pulmonary embolism (PE), the deep venous thrombosis (DVT) is not evident at the moment of PE diagnosis. The underlying factors and the origin of PE in these patients are not completely understood: missed DVT, embolization of DVT in its entirety, or de-novo PE being possible explanations. The aim of this study was to evaluate the differences in PE patient with or without co-existing DVT. Sixty-three consecutive PE patients were included. Whole leg bilateral Doppler compression ultrasound was performed to all patients. The PE location and extension, C-reactive protein, platelet count, hemostatic markers FV, FVIII, FXII…
High endemicity of human fascioliasis between Lake Titicaca and La Paz valley, Bolivia.
1999
Over a 6-year period, an epidemiological study of human infection by Fasciola hepatica in the Northern Bolivian Altiplano was carried out. Prevalences and intensities were analysed from coprological results obtained in 31 surveys performed in 24 localities and proved to be the highest known so far. The global prevalence was 15.4%, with local prevalences ranging from 0% to 68.2%. Significant differences between prevalence rates were detected and the highest prevalences were in subjects aged20 years. However, prevalences showed no gender difference. The global intensity (eggs per gram of faeces, epg) ranged from 24 to 5064 epg and showed arithmetic and geometric means respectively of 446 and …
